About me

I started coding in 2015 as a computer engineering student and have shipped production AI since 2024. At OptioAI I’ve delivered 8 production AI systems, 5 chatbot and agentic systems and 3 analytics platforms, for enterprise and government clients across Southeast Asia and the Gulf, owning each from pre-sales scoping to handover. Outside work I build my own apps and run a 51-container home server, which also hosts this site.
